The acid number and hydroxyl number can vary depending on theapplication. For example, though the acid number for waterborne coatingsis not intended to be limiting by the following, the acid number forwaterborne coating applications can be about 10 to about 100 to impartsufficient water dispersibility after neutralization. Although notintended to be limiting, the acid number for solvent-based coatingapplication can be about 20 to about 50 for better solubility and lowersolution viscosity. Although not intending to be limiting, the hydroxylnumber can be about 40 to about 100 for crosslinking withhydroxyl-active crosslinkers such as, for example, amino resin (oraminoplast) and isocyanate resin. Although not intending to be limiting,for dual crosslinking systems, for example, a coating formulationcontaining both amino and epoxy crosslinkers, the hydroxyl number can be20 to 80 or 30 to 80 or 30 to 75 and acid number can be 10 to 50 or 20to 50.

Thestirring continued at 85° C. for 60 min., then the reaction vessel wascooled to 40° C. before the resulting dispersion was poured out througha standard 260 micron paint filter. The resultant translucent,homogenous dispersion was analyzed for particle size using a DLSinstrument (mean particle size about 25 nm). After 8 months storage atroom temperature, this dispersion remained a free flowing dispersion anddisplayed no significant changes in particle size or resin molecularweight. This demonstrates the dispersion's stability.

Theproduct was a viscous mixture that was cooled to room temperature toform a solid which was collected for analysis. (Tg 42° C.; Mn 3035; Mw8436; PDI=2.77; acid number 29; hydroxyl number 42)

Example 10 Synthesis of DMPA-Containing Polyester I with NPG—withoutTMCD

The reactants: NPG (22.91 g, 0.22 moles), DMPA (7.38 g, 0.055 moles),CHDA (30.13 g, 0.175 moles), adipic acid (10.96 g, 0.075 moles),catalyst Fascat 4102 (butyltin tris-2-ethylhexanoate, 0.31 g), andtris(2,4-di-tert-butylphenyl) phosphite (0.07 g), were charged to a500-mL round-bottom flask equipped with a mechanical stirrer, nitrogeninlet, and distillation arm with graduated cylinder to collect water.The reaction mixture was allowed to react under nitrogen at 190° C. for50 min., at 210° C. for 50 min., 230° C. for 50 min., 240° C. for 50min., 240° C. under 100 torr vacuum for 10 min. After this applicationof vacuum, the reaction mixture gelled rapidly, forming an unusableproduct.

Example 11 Synthesis of DMPA-Containing Polyester J with NPG—withoutTMCD

The reactants: NPG (59.99 g, 0.576 moles), DMPA (19.31 g, 0.144 moles),CHDA (103.31 g, 0.6 moles), catalyst Fascat 4102 (butyltintris-2-ethylhexanoate, 0.79 g), and tris(2,4-di-tert-butylphenyl)phosphite (0.18 g), were charged to a 500-mL round-bottom flask equippedwith a mechanical stirrer, nitrogen inlet, and distillation arm withgraduated cylinder to collect water. The reaction mixture was allowed toreact under nitrogen at 190° C. for 75 min., at 200° C. for 110 min.,200° C. under 100 torr vacuum for 20 min., 200° C. under 5 torr vacuumfor 25 min., 200° C. under 1 torr vacuum for 55 min. The product was aviscous mixture that was cooled using dry ice to form a solid which wascollected for analysis. TMCD permits the synthesis of resins with higherTg, as in Example 6. (Tg 20° C.; Mn 1721; Mw 10557; PDI=6.13; acidnumber 39; hydroxyl number 49). This reaction required careful controlto prevent gelation, and resulted in a higher PDI with lower Mn thanTMCD analogues. The tendency for gelation with reactive diols such asNPG increases the difficulty of targeting key properties such asmolecular weight, acid number, and hydroxyl number, and limits themaximum obtainable values.

Example 12 Preparation of Aqueous Dispersion 2

DMPA-containing polyester with NPG (polyester J)—without TMCD was firstground to about 6 mm pellets, which were used to prepare a 41 wt %solids dispersion in a Parr reactor. The resin pellets (40 g) were addedto the reaction vessel with distilled water (61.13 g) and DMEA (1.61grams) as the neutralizing agent. The amount of DMEA added (65% ofcomplete neutralization) was calculated from the acid number of theresin. The Parr reactor was assembled and the contents heated to 85° C.under rapid stirring. The stirring continued at 85° C. for 60 min., thenthe reaction vessel was cooled to 40° C. before the resulting dispersionwas poured out through a standard 260 micron paint filter. The resultanttranslucent, homogenous dispersion was analyzed for particle size usinga DLS instrument (mean particle size about 20 nm). After 3 monthsstorage at room temperature, this dispersion had begun to form solid,non-dispersed material, and large sized particles (larger than 1 micron)were observed in DLS. Both of these demonstrate the dispersion'sinstability.

Example 13 Synthesis of DMPA-Containing Polyester K with CHDM—withoutTMCD

The reactants: CHDM (74.7 g, 0.518 moles), DMPA (19.31 g, 0.144 moles),CHDA (103.31 g, 0.6 moles), catalyst Fascat 4102 (butyltintris-2-ethylhexanoate, 0.79 g), and tris(2,4-di-tert-butylphenyl)phosphite (0.18 g), were charged to a 500-mL round-bottom flask equippedwith a mechanical stirrer, nitrogen inlet, and distillation arm withgraduated cylinder to collect water. The reaction mixture was allowed toreact under nitrogen at 190° C. for 75 min., at 200° C. for 110 min.,200° C. under 100 torr vacuum for 20 min., 200° C. under 5 torr vacuumfor 25 min., 200° C. under 1 torr vacuum for 10 min. After this, thereaction mixture gelled rapidly, forming an unusable product.

Example 14 Synthesis of DMPA-Containing Polyester L with CHDM—withoutTMCD

The reactants: CHDM (83.06 g, 0.576 moles), DMPA (19.31 g, 0.144 moles),CHDA (103.31 g, 0.6 moles), catalyst Fascat 4102 (butyltintris-2-ethylhexanoate, 0.89 g), and tris(2,4-di-tert-butylphenyl)phosphite (0.21 g), were charged to a 500-mL round-bottom flask equippedwith a mechanical stirrer, nitrogen inlet, and distillation arm withgraduated cylinder to collect water. The reaction mixture was allowed toreact under nitrogen at 180° C. for 75 min., at 190° C. for 110 min.,190° C. under 100 torr vacuum for 20 min., 190° C. under 5 torr vacuumfor 25 min., 190° C. under 1 torr vacuum for 30 min. The product was aviscous mixture that was cooled using dry ice to form a solid which wascollected for analysis. (Tg 32° C.; Mn 2717; Mw 9585; PDI=3.52; acidnumber 29; hydroxyl number 60). This reaction required careful controlto prevent gelation. The tendency for gelation with reactive diols suchas CHDM increases the difficulty of targeting key properties such asmolecular weight, acid number, and hydroxyl number, and limits themaximum obtainable values. TMCD permits the synthesis of resins withhigher Tg, as in example 6.

Example 15 Preparation of Aqueous Dispersion 3

DMPA-containing polyester DMPA-containing polyester (polyester L) withCHDM—without TMCD was first ground to about 6 mm pellets, which wereused to prepare a 41 wt % solids dispersion in a Parr reactor. The resinpellets (40 g) were added to the reaction vessel with distilled water(60.41 g) and DMEA (1.88 grams) as the neutralizing agent. The amount ofDMEA added (95% of complete neutralization) was calculated from the acidnumber of the resin. The Parr reactor was assembled and the contentsheated to 85° C. under rapid stirring. The stirring continued at 85° C.for 60 min., then the reaction vessel was cooled to 40° C. before theresulting dispersion was poured out through a standard 260 micron paintfilter. The resultant opaque, homogenous dispersion was analyzed forparticle size using a DLS instrument (mean particle size about 300 nm).This dispersion resulted in a larger mean particle size than TMCDanalogues with similar acid numbers (as in example 8). Larger particlesizes may not be useful for certain applications, and smaller particlesizes indicate increased dispersibility. After 9 months storage at roomtemperature, this dispersion had begun to form solid, non-dispersedmaterial, and large sized particles (larger than 1 micron) were observedin DLS. Both of these demonstrate the dispersion's instability.

Example 16 Synthesis of DMPA-Containing Polyester M

The reactants: TMCD (83.06 g, 0.576 moles), isophthalic acid (99.68 g,0.6 moles), catalyst Fascat 4102 (butyltin tris-2-ethylhexanoate, 0.88g) and tris(2,4-di-tert-butylphenyl) phosphite (0.20 g), were charged toa 500-mL two-necked round-bottom flask equipped with a mechanicalstirrer, nitrogen inlet, and distillation arm with graduated cylinder tocollect water. The reaction mixture was allowed to react under nitrogenramping from 180° C. to 230° C. over the course of 300 min., then rampedfrom 230° C. to 235° C. over the course of 90 min. At this point thereaction mixture was clear and homogenous, and DMPA (19.31 g, 0.144moles) was added to the reaction mixture. The reaction mixture was thenreacted ramping from 235° C. to 240° C. over the course of 90 min., thenreacted at 240° C. under 100 torr vacuum for 10 min., 240° C. under 5torr vacuum for 15 min., and 240° C. under 1 torr vacuum for 25 min. Theproduct was a viscous mixture that was cooled to room temperature toform a solid which was collected for analysis. (Tg 110° C.; Mn 2473;PDI=10.6; Mw 26222; acid number 42; hydroxyl number 30). The totalreaction time for this Example 16 was 515 minutes and the highestreaction temperature used was 240 degrees C. The total reaction time inExample 1 [which employs the use of adipic acid and CHDA instead ofisophthalic acid (the later as used in this Example 16)] was 225 minutesand the highest reaction temperature used was 240 degree C. although theoverall temperatures were cooler than those employed in Example 16. Thetotal reaction time in Example 19 (which also exemplified isophthalicacid] was 240 minutes at overall cooler temperatures than in Example 16.Example 19 was run after Example 16 for the purpose of analyzing whethera polyester could be made by using less strenuous conditions withoutgelling of the polyester. However, in Example 18, essentially the samereaction as in Example 16 was run using neopentyl glycol instead of TMCDat the same conditions and it gelled. This shows that the use of TMCD inan isophthalic acid containing polyester, whether or not using enhancedconditions, provides the advantage of being able to make a viablepolyester even under harsh conditions whereas substituting neopentylglycol caused gelling of the polyester.

Example 17 Preparation of Aqueous Dispersion 4

DMPA-containing polyester M was first ground to about 6 mm pellets,which were used to prepare a 30 wt % solids dispersion in a Parrreactor. The resin pellets (50 g) were added to the reaction vessel withdistilled water (115.65 g), EB (8.8 g as co-solvent), and DMEA (3.21grams) as the neutralizing agent. The amount of DMEA added (95% ofcomplete neutralization) was calculated from the acid number of theresin. The Parr reactor was assembled and the contents heated to 110° C.under rapid stirring. The stirring continued at 110° C. for 60 min.,then the reaction vessel was cooled to 40° C. before the resultingdispersion was poured out through a standard 260 micron paint filter.The resultant translucent, homogenous dispersion was analyzed forparticle size using a DLS instrument (mean particle size about 35 nm).After 10 months storage at room temperature, this dispersion remained afree flowing dispersion and displayed no significant changes in particlesize or resin molecular weight. This demonstrates the dispersion'sstability.

The reaction mixture was allowed to react under nitrogenramping from 180° C. to 230° C. over the course of 300 min., then rampedfrom 230° C. to 235° C. over the course of 90 min. At this point thereaction mixture was clear and homogenous, and DMPA (19.31 g, 0.144moles) was added to the reaction mixture. The reaction mixture was thenreacted ramping from 235° C. to 240° C. over the course of 90 min., thenreacted at 240° C. under 100 torr vacuum for 10 min. During this 10minutes at 240° C. under 100 torr vacuum, the reaction mixture gelledrapidly, forming an unusable product.
